Many children will choose “

The correct answer is “>”. Why? > Because the divisor in this case is less than 1. For example, 20 ÷ ¼ > 20. Suppose you have 20 chocolate bars. If each child gets ¼ of a bar, then one bar can be shared by 4 children. So 20 bars can be shared by 80 children. 80 > 20. Item 1

N is a natural number: Some children will choose “NT”. Why? Because they think “multiplication makes bigger”. Item 5  N < N Other children will choose “AT”. Why? Because they think “a fraction times a number makes it smaller”. The correct answer is _____ Because is an improper fraction  1 >  N > N “NT”. Why? i.e., >
